45. Eliminated possibility of infinite loop in cases when changes in BLR are ignored by the server for some reason (see)
46. Parsing 12-digit memory addresses. If gcc uses the -pie flag, need to consider that a memory address of executable file will be 12-digit, and executable file will be labeled as DYN.
47. Check for existence of process file in hashgen
48. Fixed registration of Srp plugins in Windows.
49. Checking for opening executable memory in hashgen. If specified invalid process id on linux system, then program cannot open process memory and ends with segmentation fault
50. Backport of the fix from the master branch: Now CREATE FUNCTION/PROCEDURE inside CREATE PACKAGE does not require CREATE FUNCTION/PROCEDURE privilege. It's not really necessary since there are no packages in 3.0 but the patch fixes TDBB_trusted_ddl flag reset. So let it be.

11. Request only required attributes when searching LDAP
12. Add "CREATE OR ALTER" clause for policy syntax
13. Altering computed fields. If a field changes and it has calculated dependencies, it's necessary to recalculate them. Now, recalculation is performed only for string fields and provided that a types of the calculated field and the query are the same, since cannot convert integer type to string type, etc
14. All "SrpXYZ" auth methods are considered as "Srp" plugin
15. Use --as-needed for linking to avoid unneded dependencies
16. Implemented parsing of double-quoted strings in CSV adapter.
17. Ported parameter "LoginFailureDelay" from 2.6.
18. Allow to disable fields evaluating for external trigger. External trigger object now can give a hint to engine which fields will not be used and do not need to be evaluated. Properly implemented function getDoNotEvaluateField should return true, if field should not be evaluated. Index of field should start from 0. Index -1 reserved for all computed fields, so external trigger can ask engine do not evaluate computed fields.
19. Output error messages to stderr in hashgen
20. Switch -ig allows to continue restore when errors occur during parsing BLR of procedure, function or trigger
21. Implemented CSV adapter for external tables

fbjava updated to 1.1.8. Changes in fbjava since 1.1.2:

1. Do not cache permissions when accessed not from RDB context
2. Fix loading roles list when role granted on role
3. Cache user roles list and java permissions for current attachment.
4. Ignore result type for trigger functions. We want some compatibility with JavaESPUDF at least for backup-restore
5. Initial support for JRE 9+. Add new search path for libjvm. Do not restrict code from jrt://
6. Support ExternalTrigger::getDoNotEvaluateField function. Fields which should not be evaluated can be passed through annotations: org.firebirdsql.fbjava.annotations.DoNotEvaluateComputedFields and org.firebirdsql.fbjava.annotations.DoNotEvaluateField
7. Add EvaluateField annotation in addition to DoNotEvaluateField. If these annotations exists only fields from annotations will be evaluated. EvaluateField and DoNotEvaluateField (DoNotEvaluateComputedFields) are mutually exclusive. If both annotation present, RuntimeException will be raised.
8. Getting all user roles to configure security Initially, only one role is taken - current_role. but it's not right. User can have many roles active, as access rights are configured using a combination of roles
9. Support some substitutions inside first argument of java-security permission
10. Remove debug code which lead to memory leaks

fbjava_lucene updated to 2.0.8: Changes in fbjava_lucene since 2.0.3:

1. Add script with some basic permissions for java security
2. Initialize Tika parser once when on creating DocumentIndex instance. This fix improve performance of index/reindex by an orders
3. Check if blob empty and do not try to parse it. Tika parser do not like empty streams
4. Copy description blob instead direct inserting
5. Better handle identifiers symbols case in FTS$* functions and procedures Now, by default all identifiers uppercased, so FTS$CREATE_INDEX('UpPeRcAsEd', ... will create index 'UPPSERCASED', and FTS$ADD_FIELD_TO_INDEX('uppercased', 'test', 'str') will add field 'STR' from table 'TEST' to index 'UPPERCASED'. To force symbols treat as is, identifiers should be wrapped with '"'. FTS$ADD_FIELD_TO_INDEX('"lowercased"', '"Test"', '"str"') will add field 'str' from table 'Test' to index 'lowercased'.
6. Updated dependencies with known security vulnerabilities
7. Return short from indexFieldChange to fix backup restoring from 2.x. See This function will NOT work on FBJava, because it requires TriggerContext, but at least backup with such trigger can be restored.

122. Fixed CORE-6182: ExtConnPoolLifeTime acts as countdown for activity in MOST RECENT database (of several) rather then separate for each of used databases
123. Let logAndDie() call abort() on all platforms. It prevent hung when process exits (instead of aborts) and tries to release resources.

158. Backported CORE-6078: Permissions for create or alter statements are not checked
